    Question

    There are two trains A and B. A start from point

    X at 6 AM towards point Y. Another train B starts at 7 AM from point X. If they meet at 8 AM and speed of A is 50 km/hr, while that of B is 45 km/hr. Find distance between X and Y.
    A 120 km Correct Answer Incorrect Answer
    B 157 km Correct Answer Incorrect Answer
    C 145 km Correct Answer Incorrect Answer
    D 105 km Correct Answer Incorrect Answer

    Solution

    Speed of train A = 50 kmph
    Speed of train B = 45 kmph
    Time taken by train A to meet train B at 8 AM = 2 hrs
    Time taken by train B to meet train A at 8 AM = 1 hrs
    Distance travelled by train A = 2 × 50 = 100 km
    Distance travelled by train B = 1 × 45 = 45 km
    Therefore, total distance between X and Y = 100 + 45 = 145 km
